Loft Conversions Guildford

Most loft conversions in Guildford take around 4 to 6 weeks, depending on the complexity of the project and the type of property. Whether we’re working on a dormer conversion in a semi-detached home in Stoughton, a Velux loft in Pewley Hill, or a full mansard extension in a larger house in Burpham, we tailor the process to your home and your schedule.

We start with a detailed consultation and planning phase, making sure every aspect is considered in advance to avoid delays once the build begins. Our experienced team works efficiently and respectfully, with minimal disruption to your home life—something we know is especially important in busy family homes across Guildford.

We’ll keep you updated at every step, so you know exactly how your project is progressing. Our goal is to complete your loft conversion on time, within budget, and to the highest possible standard.

Absolutely. At LMB Group, ensuring full compliance with all Guildford Borough Council building regulations is a top priority. Every loft conversion we complete—whether it’s in Boxgrove, Bellfields, or the town centre—is designed to meet current safety, structural, and energy-efficiency standards.

Our team is highly experienced in navigating local building control procedures and planning requirements. From insulation and ventilation to staircase regulations and fire safety, we make sure everything is in place and approved before work begins. If your home is located in a conservation area—such as parts of Guildford Town Centre or Abbey precinct—we’ll also manage any planning applications or special permissions required.

Choosing LMB Group means choosing peace of mind. We handle the technical details so you don’t have to, ensuring your loft conversion is fully compliant, secure, and built to last.

The cost of a loft conversion in Guildford varies depending on factors like the size of the space, the type of conversion, and any bespoke features you’d like to include. For example, a simple Velux conversion in St Catherine’s may cost significantly less than a large mansard conversion in a detached property in Merrow Park.

At LMB Group, we offer a free, no-obligation consultation, where we assess your loft, discuss your needs, and provide a transparent, itemised quote. We believe in honest pricing, so you’ll always know where your investment is going.

Our goal is to offer excellent value for money while delivering high-quality craftsmanship. Whether you’re working with a modest budget or planning a high-specification build, we’ll work closely with you to find a solution that enhances your space and fits your financial goals.

We offer a full range of loft conversion styles to suit the variety of homes in Guildford. These include:

Velux (rooflight) conversions, ideal for homes with good existing head height—common in bungalows and some properties in Westborough.

Dormer conversions, perfect for maximising headroom and floor space—especially popular in Guildford’s 1930s semis and terraced homes near London Road.

Hip-to-gable conversions, often used in homes with sloping roofs, like those found in Park Barn or Burpham.

Mansard conversions, which are larger and more structural—best suited for detached or end-of-terrace homes across the borough.

Not sure which type is right for you? Our expert team will carry out a full assessment of your property and talk you through the best options based on your budget, space, and planning requirements. The result is a conversion that’s tailored to your home and lifestyle.

A loft extension is one of the most practical and cost-effective ways to add living space to your home in Guildford, without losing valuable garden space. Whether you need an extra bedroom, a home office, or a multifunctional family room, a loft extension can transform unused attic space into something beautiful and functional.

In high-demand areas like Pewley Down, Onslow Village, and Charlotteville, a loft extension can also significantly increase your property’s market value—making it a smart long-term investment.

Better still, loft extensions can be tailored to suit your lifestyle, with options like built-in storage, skylights, en-suites, or open-plan layouts. At LMB Group, we work with you to design a space that suits how you live, while seamlessly blending with your home’s existing character.

In many cases, loft extensions in Guildford fall under Permitted Development Rights, meaning you won’t need formal planning permission—so long as your project meets certain size and design criteria.

However, if your home is in a conservation area like Stoke Fields or Guildford Town Centre, or if you plan to alter the roof shape significantly (as with a mansard or hip-to-gable conversion), you may require planning approval.

At LMB Group, we’ll guide you through the entire process. We’re experienced in dealing with Guildford Borough Council and can handle any necessary applications on your behalf. Our team will ensure your project remains compliant and progresses smoothly from design through to completion.

Yes, a loft extension can significantly enhance your home’s energy performance—especially in older Guildford properties where insulation may be lacking. During your conversion, we’ll install modern insulation and energy-efficient materials, reducing heat loss in winter and helping your home stay cooler in summer.

We also offer Low-E glazing, sustainable timber, and can include features like solar-ready roof windows—helping reduce energy bills and your carbon footprint. Whether you’re in a period home near Holy Trinity Church or a modern property in Merrow, we’ll make sure your new loft is as energy-efficient as it is comfortable and stylish.
